This :inventionrelates to looms for weaving pile fabrics and morepart-icularly..to

Vcorresponding in general with the reeds, the

looms of thetype employing pile wiresvarranged longitudinally ofthefabric or in the i n v separated by the rods which accordingly direction'of the warps'.v .Y

The principalvobject Vof the invention is As clearly shown in Figsf and4, each of the rods 18 has near the upper end flanges l19 and 21extending transversely'frointlie 65 to vprovide improved meansforforming the loops on the pile wires, whereby the loopforming operationis a positive one precludlio ing thel possibility of missing.

The invention vfurtherv contemplates 'the' provision of novelloop-forming means constituting amaterial' and vhighly practicableimprovement over mechanisms previously used for this purpose.

Vith reference to the drawings, 1 designates the harness of a loom, 2the lay, and 3 theV pile 4 and which have at their outer ends guides 5for rotary cutters G. The nature ofthe cutting means may vary largelyand has no partV in the present invention, In the 'present instance, theindividual guides 5 are formed, as shown in Figs. 5 and 6, with a slot 7for reception of thel edges of there; spective sockets 8 in the ends ofthe pilewires 3. Clamps 9 are provided on the support 11 for retainingthe guides in proper position relative to cutters and pile wires.

. The other' ends of the pile wires 3 are respectively 'supported at theupper ends of upright blades 12 mounted in a frame 13 interinediate1 theharness and the lay. As shwniii Fig'. 2, this frame comprises twoiigirig'hts 14, 14, aiicl two herianntal 'icse wires which pass throughthe reed cutters, andare adapted to fit into -man shaft QS cf the leonithrough Appiicamnsizi 'Apriifia i925. serial 23,584.r

bars-15 and bars 15 and-*16 funcf' tion to support a series lfof uprightyrods 18 warp threads passing between and beingGO constitute verticalguides for said threads.

the endswith a hook formation 23 which fits 75 over the' top of the bar22T, and thelatter, as shown in Fig. 2 is provided with a series ofslots 17 in which the blades are seated, andy these slots are soarranged that the blades occupy positions opposite the spaces between 80L the rods 18. Also the cross bar 22 is voffset transversely from thatside of the frame ad# jacent the harness so that only the inwardlyoffset and comparatively thin and flexible upper ends 24 of the bladeslie between the 85 guide rods 18. As shown in Fig. 1, theupperextremities of the blades ylie opposite the flanges 19 and 21, andat a pointimmediately below the flanges each of the blades has aforwardly projecting tongue 25 over 90 which fits one end of a flatsleeve 26-in the other end of which lits the associated pile wire 3. Thesleeve 26 is preferably soldered or otherwise attached to the tongue25,',and with the guides 5 secured to the respective 95 pile wires",there is provided an easy method for withdrawing the pile wires in theevent of repairs being required. After cutting the loops and releasingthe clamps 9, itwill be apparent that the wires may be withdrawn Lwithout diliiculty.

Mounted for longitudinal reciprocation on the'frame 13 below the crossbar 22 is a beam 27, and the lower recessed endsof the blade 12 lit downover this beam and extend into 105 transverse slots whereby thelongitudinal reciprocatory movement of the beam results in oscillationof the blades about their fulcrums on thev bar 22. The beam is shownactuated in the present instance from tllie tie medium tif-tt the, shaftmi a. nam

lever 3l mounted for horizontal oscillation about a pivot 32 on abracket 33, the latter gaging the cani while the other is pivotallysecured at 34 to the beam 27.

In the present instance I have shown two sets of'heddles 35 and 36. Theheddle-35 has two eyelets, one for the pile warp 37 and the other forthe three binder warps 38; while the heddle 36 has a single eyelet for abinder warp 39. Obviously the number and character of the warp threadsmay .vary widely according to the nature and desired characteristics ofthe fabric.

The mode of operation of this type of loom is in general well known tothose acquainted with the art. The heddles 35 and 36 reciprocateoppositely to form the shed for passage of the shuttle or shuttles andthe lay operates in the usual fashion to beat in the wefts or fillerthreads deposited by the shuttle. The eyelet holding the pile warp 37 isso positioned in the heddle that on each upward stroke this warp iscarried above the top of the blade 12 and pile wire 3.

In the normal extreme positions of the beam 27, determined in thepresent instance by the cam 29, the upper ends of the blades 12 lieagainst one or other of the faces of the respective rods 13 betweenwhich the individual blades lie, and when so positioned( the flange 19or 2l, as the case may be, of

the rod 18 against whichy the blade lies guides the warp 37 in itsdownward movement over and past the upper end of the blade, as will bereadily understood by reference to Figs. 3 and 4 vof the drawings. Thepositions of the blades accordingly determine on which side of thevarious pile wires 3 the warp 37 is brought down, and the cam may be soformed and timed that this warp is successively brought down on oppositesides of the wires. The warps 37 being tied down by the filler threads,passed over the warps and under the wires when the warps are depressedform loops over the wire, as indicated at 41. in Fig. 1, and these passinto contact with the cuttersf which sever them at the top to -form thepile.

By extending what in eect is the pile wire upwardly between the rods 18so that they lie between the guide flanges 19 and 21, and by actuatingthe wires as described, it is impossible for the warp 37 to pass downthe wrong side of the pile wire, and the loopforming operation isaccordingly a positive one.

A considerable advantage of the construction is found in the loosemounting of the blades 12 which permits them to be lifted freely fromthe support. This avoids much possible breakage. It will also be notedthat the flexibility of the upper ends of the support blades provide fora bearing of these parts against the warp guides without too Y` tineadjustment of the parts.

, There may be considerable Vmodification without departurefrom ,theessential fea-V turesof the inventiomand I do not wish to` ing said wirefor vertically*reciprocating a pile warp said wire.
